Dragon Warrior 4 for the original Nintendo. 4 separate individual story lines that all come together for an epic 5th story line. My replaying of that game over and over again is the sole reason I never wanted a Super Nintendo.

Had this back in the day, still is my favorite fighting game of all time. Had a W/L record of 601-0 when I played that I've played my fair share of fighting games through the years and this will always be my favorite.

T.J. Combo was the SH!T

Some footage:

There was a sequel on the N64 that was also good but I liked the orignal more.

My favorite video game is probably Mr. Do. I used to spend hours at the local bowling alley plunking quarters into that thing and occasionaly I'd uncover a diamond and win a free game. Many games today you can save and start from where you left off and have it beat in a few weeks but back then in the coin-op days it was all about skill and memory and the games got faster and harder the higher level you played and I loved the challenge.

NES and sNES as a kid = Zelda and NBA Jams
My cousin and I spent countless hours shredding Zelda, as Mario became childs-play. As much of a Knick homer as I was, Ewing and Starks could not stop Alonzo and LJ

Arcade as a teen = Street Fighter
This game was played in mall arcades, local pizzeria's as well as other hot spots. The trash talking, the actual fist fights, the drama. In the early 90's you listened to hip-hop and could throw 30 fireballs, followed by a sweep kick and "shoruken" uppercut.

PC as an adult = SOFII (Solider of Fortune 2) MP
Anyone who was an online gamer in the early 2000's knows this game basically set the bar for modern day military first person shooters. The was COD from a decade ago...

I'd have to say The Walking Dead: Season 1 from Telltale Games. It really is everything I need in a game as an adult. Great story, manageable length for someone without a lot of free time to game, and a low price point.

pitfall for the atari 2600. First game system owned back in the day and this one just sucked me in as it was finally different from pong and tanks, etc. Castlevania 1 & 2/Rad Racer/"baby mario"/rygar/first few megamans and metroid/mortal kombat all are in the top few too.
